To all whom t may concern.' i

Be -itv known that we, EMIL A. PETERsoNf `and WILLIAM J. MCGINNis, citizens of the United States, and residents of Appleton, in of Outagamieand State of `Wis consin,` have invented new and useful Improvements in Hydraulic Control Attach` ments for Beating, Bleaching, and'Washing Engines, of whichthe following vvis a description, reference being hadto'theaccompanying drawings, which are a part of this specification.

The present invention relates to certain new and useful improvements 1n hydraulic control attachments for beating and washing machines and refers more particularly to beating, bleaching and washing enginesespecially adapted for use in preparing stock in themanufacture of paper.

' The present devices now on the market for adjusting the beating roll and the washer employa jack screw which has proven veryunsatisfactory in that the movement of theroll. and washer from one position f to the. other is jerky and further that such a device lacks the flexibility required in a device of this character.

With these inherent objections in mind, our invention has for one of its objects to. provide hydraulic means for vertically adjusting the beating roll and washer ofk a paper pulp preparing machine which will have the desired flexibility and which will be ca-` pable of fine adjustment.

Another object of the present invention isy to provide hydraulic adjusting means for a beating roll which will have means for auto-A matically permittingthe pressure to escape therefrom as the stock becomes finer, and

standard and hydraulic cylinder forengaging one end of a lever journally supporting thebeating roll and having its other end` fulcrumed to another supporting standard` `which will appear asy they f of the principles thereof, and in which:

lWitli the above and other objects in view description pro ceedsour invention resides in the novel construction,l combination and arrangement of parts substantially asfhereinafter described yand ymore particularly dened by the appended claims, it being understood that such changes in the precise embodiment of the hereindisclosed invention may be made as come within the scope of the claims;

In` the accompanying'drawings, we have illustrated one complete example of the physical embodiment of our invention, constructed according` to the'best mode we have so far devised for the practical application Fig. l isa side 'view of a portion of a paper stock beating and washing machine equipped with our invention, parts being broken away and in section to more clearly illustrate the details of construction.

Fig. 2 isa top plan view thereof, parts being brokenfaway and in section to illustrate various structural details.

Fig. 3 is a sectional view through one portion of the machine 0n the line 3 8 of Fig. 2, parts of the hydraulic cylinder and the yoke member connected with'the washer being broken away and insect'ion. y

` F igd -a diagrammatic view, part in section andpart in elevation illustrating the hydraulic ramsfor operating the beating roll and the washer and their various pipe connections, and

Figure 5 is a view part in sectionand part in elevation taken through the relief valve for governing the descent of the roll `Referring now moreiparticular-ly to the accompanying drawings, 5 designates av paperstock beating andwashing machine container having disposed therein a central wall or partition 6, spaced from the' ends of the container and dividing the same into *twocommunicatingsections; 7, a beating roll or rotor disposed in one of the sections and having its supporting shaft 8 j ournalled in bearings 9 securedto levers "LO (to be later described) `mediallyoftheir ends and 11, a washer disposed inthe other section of the container and mounted upon a supporting shaftv 12 journalled in bearingsl'as later described.

The beatingroll or rotor-.7 is rotated by .meanso a drive pulley 14. -mounted on its .togetherwith water at a desired level and the rotation of the beating rolland the washer causes the stock to pass through the two ysections of the container. The roll 7 coacts Ywith a bed plate 7 knives and bed yknife receptacles, to coinn'iinute-the stock as-it passes therebetween,

f the ystockbeing forced up and over a back- 'fall 1T and vthen travels around through the container, the water being cleansed from the impurities which float upon the top by means .ofthefwasher 11 which revolves in an oppo site directiontoithe material. As the stock becomesiineig-thevroll 7 is lowered to decrease the space between it and the bed plate 7 until the stock is thoroughly commiiiuted.

All of the Vforegoing mentioned operation is well `known `in the art, and our invention resides .in the novel means employed for raising and` lowering` the beating roll 0r vrotor 7 and in adjusting thewasher 11 as herein- .after described.

Disposed adjacent each side of the con tainer l5 is `a pair of vertical supporting` standards 18 and 19 with which the levers lQareconnected. The standards 18 and 19 have their lower ends reinforced or enlarged as at 2O andftheadjacent standards 18 and 19. are connected together .at their lower portions byineans of a skeleton brace construcvtion 21 as best. shown in Fig. 1. yEach lever 10 has one end eXtended into its adjacent standard 18 through a slot or groove 22 and pivotally secured therein, as at 23,` and its other end projected into the adjacent standard 19 'through a slot or groove 24 and is connected, by means to be later' described,

withapiston25 slidably mounted within cylinder 26formed in the lower enlargement 2O of the standards 19. From this .structure it will be obvious that the standards 18 function as fulcrums for the levers 10.

0 T heend of each lever 10 disposed within itsl adjacent standard 19 is 'formed witha vertical bore 27 which is flared 'upwardly and outwardly and has mounted therein the `of the leverldadjacent its bore 2? upper end of a connecting rod 28 vwhich is .pivotedas at 29 to the piston 25.

shown .in vFig'. 1a shoulder '30 is formed on the rod28 and impinges the under side and has secured :t0 itsiupper end disposed above the top face ofthe lever 10 a pair offloclring nuts 8 1. Cllhe flaring or taperingy of the bore 2'? and the pivotal connection 29 between the Arod `r28 and piston 25 permits the vertical movementofthe endlof theflever 10 as will including bed v, l v l l lh Q. f) :lief line 87 having therein a spring actu- As best be apparent, and to prevent the end of lever 10 disposed within the adjacent standard 19 from binding againstv the ,inner wall4 of the standard, the end of the lever'is slightly curved as at 32. l,

Both cylinders 2G are coupled together by means of a pipe 33, the ends of which enter the cylinder as at 8l, andcominunicating with the pipe 38 intermediateits ends 34 is a supply or intake pipe connected with suitable means for supplying fluid under pressure and controlled by means of a valve Staand also .communicating with the .pipe 33 intermediate its ends is a drain pipe 5'? having therein a control valve To raise the roll 7, valve is closed by movement 0f its handle 38', and the valve 86. opened by means of its handletll` which Aallows fluid .under pressure to pass from the Vpipe 35 through pipe and into the cylinders 28 where the fluid iinpinges against Vthe pistons 25and urges them upwardly,

carrying with them the roll Tby reasonof their connections with the levers il). as before described.

ln order to chech or limit the .upward movement of thepistons 25 and the elements `connected therewith to prevent damage or injury tothe machinery, we provide-a valve 89 in the pipe intermediate valve 36 and vpipe .33 which is `normally held open by means of a lever 40 pivoted to the topI of one and'thus `checking 'the upward movement of 4both pistons 25. .As the drain valve 38 is closed, the pistons 25 .will be retained in their upward position aswill be understood. lll/Then the upward movement'of the pistons 25 `is checked or stopped rby the automatic `devicejust described, the valve 36 is then closed so that the automatic lowering device now aboutvto bedescribedamay function properly. ,im

` Disposedwithin the pipeline Sbetween and `pipe line-33 isy an auxiliary rend relief rabe-i5. "The valve l5 is of any All-lrnown construction and in the present 1, is illustrated as comprising a casing having` an end 7 2 connectiblewith the relief-linee! and aneiid T3 connectible with the line vSi?,,through the line 37. The casing has a partition 74 therein disconnecting ends 7 and w78 andihaving'an opening therein vn orrrnilly closed by a `valve 75normally yieldingly .urged tof closed position -by a 'is dropped gradually as the stock becomes liner and the reliern valve l automatically effects this adjustment. The weight oit the rotor or beating roll 7 is supported somewhat by the stock passing between it andthe bed plate 7 and as the stock-becomes liner the density of the material assisting in supporting the rotor or beating roll decreases and consequently increases the pressure With-v lhe in the cylinders 26 and the pipeline relief valve is adjusted sothat as the pressurel is xincreased as described, it will be operated to open the auxiliary drainline 37" and 'allow the rotor or beating'roll' tobe dropped. y llhenl the rotor hasdropped suihciently to'hzwe a portionvv of'its Weight supported by the sto-ck, the relietvalve will automatioally close.` The downward limit of movement of the rotor or vbeating roll' 7 is governed by means ot' a jaclrserewf carried byfa socket or standard 47 formed von the braces2l and engaging the endsof thelevers l0 adjacent the standards 1.9.

Thebearings 13 of the Washer supporting shaft l2 are shaped to have sliding engage ment with a pair otxvasher 'posts 48 secure-d to the partitions 6` and the adjacent outer Wall ot the containeix rlhe Washer posts have .their upper ends connectedby means ot a ytrznisverse member i9 to Ithus provide a supporting and guiding iframe. for the Washer. ll'. The bearingsv 13 are movable along the washer posts and tolmove the-same to eiiieet theadjustinent ofthe. Washer 1l, We

' provide a pair otL connecting rods `50 conneotedto the bearings as at 5l and having their upper. ends passed through guide openings 52 "formed in the. upper ends of the Washer posts 48 and connectedas at slto the Yrms 54. of a yokemember 55.v

ylhe yoke surrounds a. vertical cylinder 56 which has its lower. end secured to and closed by transverse member 49 and Aits upper end provided with acap 57 having therein a central bore through which passes a piston rod 5S having its lower end connected to a piston 59 mounted Within the cylinder and its upperl endv secured to the yo-lre as at 60. The member 449 has a threadedopening therein communicating with the cylinder 56 Ain which is securedy the end or a supply pipe` 6l' which is connected with suitable meansr'ffor supplying fluid underL pressure andhas therein'acontrol rave 62 having an operating handle 672'. 'ommunicating with the supply )ipe 6l intermediate the cylinder and control, valve 62 is a drain pipe line 63 having thereineo control valve 6l having a control'handle 6e. To raise the Washer ll the valve 6a is closed'and valve 62 opened allowing fluid under pressure to impinge against the piston 59 and raise the yoke and consequentlythe Washer ll by means olA its connections therewith.

The upward movement of the Washer ll is controlled by a counter-balance lever lia-ving one end connected to `a normally ope-ned vali-e 66 in the line 6l intermediate valve 62 and the cylinder 66 by means ot ak linlr64- and having its other end counterbalaneed by a Weight 68. The lever 65 is medially pivoted'to oneol1 the Washer posts 6 and is engageable by the adjacent portion of shaftalfvivhen it reaches its upward limit oi movement, thus overcoming Weight f verse ymembery 9. The usual drain for the Washer lli is vprovided as at 69 having a spout or outlet 70 telescoped nf'ithin a bowl 7 l 'adapted to be connected to anoutlet pipe, not shown. The bowl 7l is secured. to the adjacent' side yWall of the container 5 and serves as a support for the adjacent Washer post' 48,

' From the 'foregoing description. taken iu connection with the accompanying' drawings, it Willbe readily apparent to those skilled in the lart to which an invention et this character appertains., that the adjustment of the rotor or beating' roll 7 and the Washer ll may be readily obtained and that'the movements of the same will not in any man' ner interfere with their driving connections andthat the adjustment may be made as exactas maybe desired. v
